Inventor Guido Fetta describes EMdrive related propellentless Cannae drive aka Q drive system

Guido Fetta describes created unbalanced electromagnetic forces within the chamber. Guido says summing the lorentz forces has a propellentless force.
Guido Fetta, inventor of the Emdrive related Q-Drive.

Fetta, an independent inventor with a background in chemical engineering, explains that the drive is a “superconducting resonating cavity.” An imbalance in the cavity, Fetta says, creates thrust.

Fetta had tested a superconducting version of the “Q-drive” or Cannae drive on 13 January 2011 several yearsprior to the Eagleworks test campaign. The RF resonant cavity was suspended inside a liquid helium-filled dewar. The weight of the cavity was monitored by load cells. Fetta theorized that when the device was activated and produced upward thrust, the load cells would detect the thrust as change in weight. When the Cannae drive was energized by sending 10.5 watt power pulses of 1047.335 MHz RF power into the resonant cavity there was a reduction in compressive force on the load cells consistent with thrust of 8-10 mN. The results have not been published in the scientific literature, but were posted on Cannae LLC’s website.

Wrightspeed unveils new turbine range extender for medium- and heavy-duty electric powertrains; 30% more efficient than current microturbine generators

Wrightspeed Inc., a developer of range-extended electric vehicle powertrains for medium- and heavy-duty vehicles (earlier post), has unveiled the Fulcrum, a new proprietary turbine generator for use in its Route family of electric powertrains (Route for Class 3-6, Route HD for Class 7-8). The new 80 kW Fulcrum is a radial inflow, axial turbine, intercooled and recuperated. Fulcrum is a single shaft machine, the generator runs at turbine speed (~100,000 rpm). Weighing in at 250 lbs (113.4 kg), the Fulcrum is approximately 1/10th the weight of its piston generator counterparts and it is designed to have a 10,000-hour lifetime.

The use of microturbines in autos has been explored for a long time, with a number of manufacturers actively exploring the potential shortly after World War II: these included Rover in the UK; Fiat’s Turbina, introduced in 1954; a Chrysler Plymouth prototype turbine car also introduced in 1954; GM with its Firebird prototypes, also introduced in the early 1950s; and the limited production run Chrysler Turbine Cars, introduced from 1962-1964.

The Japanese began a 100 kW automotive ceramic gas turbine (CGT) project in 1990 and concluded it in 1997. The US Department of Energy (DOE) in the 2000s ran a cooperatively funded, multi-path technology development program called the advanced microturbine system (AMTS).
